Collaborative Robot Assisted Language Learning - CoRALL

Abstract: Studies of spoken human-robot interaction (HRI) with the application for language learning have noticeably gained popularity within the HRI community [1]. Among the learning activities studied in Robot assisted Language Learning (RALL), speaking skills development has seen a lesser number of contributions, with even less studies aimed at adult subjects. In this one-year seminar, I will present our work focused on Robot Assisted Practice Conversations, specifically aimed at the visual characterization of uncertainty (or confusion) in adult second language learners. Our current work intents to detect uncertainty events and adapt the dialogue system to react appropriately.

Plans for future work will be discussed as part of on-going projects of closed-topic dialogue generation -and evaluation- for language learners, and the use of group behavior and HRI to improve learning outcomes.
